The kit includes one Motorola 2.5 Bar Map sensor,detachable connector and 12" of colored wire with online instructions to hook it into your stock MAP wiring.
Upgrading from a stock Honda/Acura Map sensor that can only read ~10 psi of boost will allow you to run up to ~21.75 psi of boost as well as set a boost cut in your engine management. This safety feature has saved many motors from overboosting due to many random factors/problems that occur on Turbo Charged vehicles. This ECU map sensor kit is extremely linear which makes for ease of tuning using the most common Honda/Acura ECU Editors available. (Crome, Neptune, Hondata, Uberdata, TurboEdit & BRE)
